Unit is used, but in excellent A stock shape. No scratches or dings. Tested and works perfectly.
The X75 is a 2-channel dual source power amplifier with autosource switching. It features two audio line inputs with a loop out to another zone, receiver, or device from Line 2 source. This amplifier can be used for power upgrades in specific zones, for speaker selector or volume control systems. The X75 is a Class D amplifier rated at 75 watts per channel into 4 ohms, and 60 watts into 8 ohms. With the Stereo/Bridge Mono switch in Bridge Mono position, both amplifier channels are combined for a higher powered mono output. In Bridge mode the X75 is rated at 160 watts of power into a single 8 ohm load.

Overview: The Russound X75 is a dual source 2-channel power amplifier. The X75 features volume and balance controls, as well as A/B speaker switching on the front panel.
Power Output: The X75 is a Class D amplifier rated at 75 watts per channel into 4 ohms, and 60 watts per channel into 8 ohms. Both amplifier channels can be bridged for a higher power mono output of 160 watts into a single 8 ohm load (The Stereo/Bridge switch on the back panel should be in the Bridge Mono position when bridging.)
Signal Sensing Inputs: The X75 can be turned on manually or automatically by setting a switch on the rear panel. For manual power, the front panel power switch turns the unit on or off. When set to automatic, the unit will power on when music is sensed on either RCA input connector. Once the signal is no longer detected, the unit will automatically shut off. Signal sensing inputs allow the amplifier to easily integrate with multi-room audio systems and home theater components.
Thermal Protection: The amplifier is designed with a special circuitry that protects the unit under a thermal overload condition. Thermal protection mode will only engage when the unit has been run at high volume for extended periods without adequate ventilation and/or when speaker impedances are below the minimum levels. For proper ventilation, it is recommended that the amp have a minimum of 8-1/4" of clearance above, 5-1/8" of clearance behind, and 2-7/16" of clearance in front of the unit.
Short Circuit Protection: In addition to thermal protection, the X75 also has special circuitry to protect the amplifier from short-circuit conditions. This can be caused by a faulty speaker or when speaker wires come in contact with each other. When this condition occurs, the amplifier will shut down until the short circuit is corrected.
Unswitched Outlet: The X75 has a built-in AC outlet on the back panel for powering a device such as a small subwoofer or an audio component. The outlet provides power as long as the X75 is plugged into a live outlet, regardless of whether or not the amplifier is powered on. The outlet is rated at 120 volts and 400 watts.
